Bacteria colonizing the rhizosphere of plants (=rhizobacteria) play different ecological roles in their natural environment. Some are deleterious to plant growth and health, while many others are beneficial and act as both ...

Reductions in crop yields brought about by abiotic stress are expected to increase as climate change, and other factors, generate harsher environmental conditions in regions traditionally used for cultivation. Although ...

Background: Parasites can exert selection pressure on their hosts through effects on survival, on reproductive success, on sexually selected ornament, with important ecological and evolutionary consequences, such as changes ...

Chemical investigation of an acetonitrile fraction from the endophytic fungus Phomopsis sp. led to the isolation of the new natural product 2-hydroxy-alternariol (7) together with the known compounds cytochalasins J (1) ...

From the plantCentaurium cachanlahuen, swertiaperenine1, swercherine2, decusatine4, oleanolic acid5 and the xanthone 1,8-dihydroxy-2,3,4,6-tetramethoxy-9H-xanthone3 were isolated and characterized.

Fusarium fujikuroi and Fusarium proliferatum are two phylogenetically closely related species of the Gibberella fujikuroi species complex (GFC). In some cases, strains of these species can cross and produce a few ascospores. ...

The plant kingdom represents a valuable source of natural products of commercial interest. These compounds, named secondary metabolites, are not essential for the survival of plants, but confer them some advantages that ...
